Mid Sweden University leads development of digital color x-rays

22.05.2007
In the future doctors will be able to find more tumors at an early stage while using a smaller x-ray dose for each examination. Color x-rays offer new possibilities for medical diagnoses. This spring Mid Sweden University is presenting three dissertations in the field of digital color x-rays.

Digital color x-rays are based on the same advanced technology that is used when nuclear physicists look for new elementary particles. The great scientific challenge in constructing a color x-ray camera is to be able to shrink the large-scale detection equipment used by nuclear physicists to the microscopic format.

The readout electronics for each pixel in the camera's picture sensor must be squeezed into an area of 55 x 55 µm, and what's more be x-ray safe. The Mid Sweden University researchers have solved these design problems. Furthermore, they have shown that Medipix2 can be used to reduce the radiation dosage in dental x-rays. Industry also expects to be able to use the technology to see the consistency of materials using x-rays.

"With our digital color x-rays it will be possible to cut the radiation risk in half for x-ray examinations," says Börje Norlin.

Using advanced computer simulations of the next generation of x-ray cameras, Mid Sweden University has also developed ways to enhance the quality of color x-rays.

These cameras will have higher resolution and be able to show more colors of higher quality.

In connection with these dissertations, CERN will be holding one of its quarterly meetings in Sundsvall, Sweden, to discuss the further development of color x-ray technology.

The dissertations are:

Xavier Llopart, Design and Characterization of 64K-Pixel Chips Working in Single Photon Processing Mode (Xavier Llopart is stationed at CERN in Geneva.)

Jan Lundgren, Simulating Behavioral Level On-Chip Noise Coupling

Börje Norlin, Characterization and Application of Photon Counting X-ray Detector Systems

Im Focus: Quantum optical sensor for the first time tested in space – with a laser system from Berlin

For the first time ever, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments like space – a prerequi-site for finding answers to the most challenging questions of fundamental physics and an important innovation driver for everyday applications.

According to Albert Einstein's Equivalence Principle, all bodies are accelerated at the same rate by the Earth's gravity, regardless of their properties. This...

Im Focus: Interfacial Superconductivity: Magnetic and superconducting order revealed simultaneously

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
